GUSTAV DIETERT, OF KERRVILLE, TEXAS.

SPECIFICATION forming' part of ietters Patent No. 400,195, dated. March26, 1889.

Application iiled May 31, 1888. Serial No. 275,567. (Model.)

To all wiz/0m t may concern:

Be it known that I, GUSTAV DIETERT, a citizen of the United States,residing at Kerrville, Kerr county, Texas, have invented certain new anduseful Improvements in 'Windmills, of which the following is a fullspeciiication.

My improvements are designed more particularly for use in connectionwith that class of wind motors known as the vertical wheel g and thesaid improvements consist in certain features of novelty, which will nowbe described, with reference to the accompanying drawings, and then morespecifically pointed out in the claims hereto annexed.

In said drawings, Figure I is a side elevation of a windmill, showing aportion of the wheel and also a portion of the tail, and the trellisworkor tower omitted. Fig. In is a detail view of the ball-and-socket jointhereinafter referred to. Fig. Ib is a sectional view taken on the line bb, Fig. I, Fig. II is a plan View of the same. Fig. III is a detailview,partly in vertical section, showing the crown of the tower with thewheel-support fitted thereon, portions broken away. Fig. IV is a detailview looking in the direction of the arrow in Fig. Il, the arms forsupporting the wheel being broken away.

1 represents a portion of the wind-wheel upon the shaft 2which latter isjournaled in suitable bearings or boxes, 3, carried by the two arms 4;.These armsare preferably cast integral with the sleeve or collar 5,which, together with said arms, forms the wheel-support.

6 is the part which will be hereinafter designated the crown of thetower, which may be secured in any suitable manner to the top of thetrelliswork of which the tower is formed. Projecting upwardly andaxially from this crown 6 is a tenon 0r journal, 7, around which thecollar or sleeve 5 is adapted to revolve, the latter resting upon ashoulder or flange, 8, on said crown. Formed around this tenon is aperipheral groove or channel, 9, in which engages a set-screw or pin,10, driven through the collar or sleeve 5 for preventing the latter frombeing lifted vertically from said tenon, but at the same time permittingits free revolution thereon. Passing vertically through the tenon and'crown 6 is a hollow shaft, 11, which at its lower end is suitablystepped'in a bearing or step, (not shown,) and at its upper end isprovided with a beveled gear, 12, adapted to be engaged by a similargear, 13, mounted upon the wheel-shaft 2.

The tail or rudder 14 is provided with a stem, 15, which latter isplanted in a stock or socket, 16, hinged to an arm, 17, the latter beingsecured to or made integral with the collar or sleeve 5, or with one ofthe arms 4, as shown in dotted lines in Fig. I. These two parts. V16 and17 are hinged together by means of a ball-and-socket joint of the usualand well-known construction, the arm 17 bearing the ball 18, while thestock 16 carries the socket 19, the latter being made in two sections,as shown in dotted lines in Fig. I and in full lines inFigs. I Ib, andprovided with a lateral groove, 21, for the passage of the arm 17 as therudder turns, and the lower section being provided with a vertical notchor groove, 20, in order to permit the tail or rudder to be foldeddownward in a vertical position when the same is to be removed or whenit is desired to have the mill remain inoperative. Secured around thisstem 15 is a ring or collar, 21, which is provided at both sides withrings 22 for the attachment of cords 23 24, the former passing aroundthe pulley 25, which is mounted in an approximately horizontal positionin the recessed end of an arm, 26, and thence over a pulley, 27, whichis mounted vertically and directly over the hollow shaft l1 in thebifurcated end of the arm 28. The cord after passing over this latterpulley descends through the hollow shaft within the reach of theoperator, whereby he may be enabled by drawing upon said cord to pullthe tail or rudder toward the wind, andconsequently throw the wind-wheelout of the wind or with its edge toward the same. The arms 26 and `2Sare preferably made integral with a bracket, 29, secured by any suitablemeans to the side of the collar or sleeve 5.

The tail is maintained in the wind by means of a weight, 30, which ismounted upon one arm of an angle-lever, 31, and held at any desiredposition on said arm by means of a setscrew, 32, it being prevented fromslipping from said arm by an ordinary stop or pin, 33,

TOO

inserted through the end of the latter. The other arm of thisangle-lever is connected by means ot' the cord 2i to the other of' saidrings 22, and the lever is pivoted by means of a bolt, 34-, to a plate,This plate is prefer ably cast integral with two converging arms, Sti,which l'orni a bracket, they being secured at their d iverging ends tothe revoluble sleeve or collar by means of; the bolts 37, as shown.

'3y the construction thus described it will be seen that the weight 23()may be placed `upon the anglewltiver to hold the tail to the wind as lonas the latter remains ai a certain velocity; but when the velocityincreases the weight will be overcon'le and the wheel and tail or rudderwill change position relative to one another.

In order that l may regulate the angle ol the wi 11d-wheel to the wind,I provide the stock or socket llt with an cutwardly-projecting arni, 3S,which it is preferable to make in tegral with the stock, and which isprovided at its inner end with the long set-screw The end oi thisset-screw is adapted to abutagainst the side ot' the arm i when the winddecreases and the weight 3() returns the rudder to its normal position,and it will be seen that by adjusting this screw the normal position ot'the rudder relatively to the windwheel maybe varied to a considerabledegree, and thus prevent the wheel from turning broadside to the windwhenever the pressure ci the latter becomes less than that of the weight30. rlhe tail is prevented from taking a downward turn by means of astay-rod, iti, which is secured to a hook, Lt1, on the yoke or brace 49,that projects from one journal box or bearing to the other over thewheel 13, and thus braces the arms 4, and this rod is secured at itslower end to an rrln, 43, which vis preferably made integral with thering or collar 2l on the stem 15. The purpose of this' arln 13 is toprevent the rudder revolving transversely to a horizontal position, asit is readily seen that if the rod 4x0 were attached directly to thestem, or even to a link in the collar thereon, the leverage would not besuticient to keep the stock in which the rudder is mounted fromrevolving on the ball of the joint.

Having thus described my inventiomwhat I claim as new therein, anddesire to secure by Letters Patent, is

l. The combination, with the revolublc wheel-support, having the yoke42, and the tail or rudder having a stem, of a ball-andsocket joint, bywhich said stem is secured to said wheel-support, a collar or ring,21,011 said stem, and a rigid arm projecting upwardly i from said ringand connected with said yoke, substantially as set forth.

2. In a windmill, the combination, with the stem 15, the collar 5, thearm 17, secured thereto, and the ball 18 on said arm, of the stock 16,receiving said stem, the socket it), made integral with stock 16,receiving said ball, and the arm 3S, made integral, with said. stock andcarrying a setscrew, as set forth.
